Dynamics of Gene Gain and Gene Loss in Bacteria... 

Various authors using different data sets, algorithms, and assumptions about the frequencies of gene loss and gene gain have come to differing conclusions about the proteome of the LUCA. The number of universal... 

The fate of introns, cont d. After its retroposilion, the ptimate RNF113B gene gained its intron, but not by de novo insertion. The intron s donor site was a double point-mutated sequence AG —> GT. The acceptor site was created by another point mutation GG —AG. The 105 bp intron contains 59 nucleotides from its previous sequence, and 46 nucleotides from the 3 UTR untranslated region. The new intron is accepted by the U2 spliceosome. The new intron was formed in the primate...
